WMSN applications have different QoS
requirements (Q) such as bounded latency (or delay) L, bandwidth
(or throughput) B, jitter J, packet loss P and energy consumption E,
so {L, B, J, P, E} ⊂ Q. Depending on the constraints, and in order to
impose them itis necessary to check whether min {ωQ(p)} ≥ Qmin or
max {ωQ(p)} ≤ Qmax, where Qmin or Qmax are the minimum or maximum
values allowed. For example, the bandwidth path constraint
ensures that min {ωB(p)} ≥ Bmin, for all valid paths.
